Cemented carbide >>> Cemented carbide roll rings for hot rolling of seamless steel tubes.
ˇˇˇˇThe lifetime of cemented carbide roll rings is 50-80 times that of conventional roll rings when they are used at tension tube reducing machines for hot rolling of seamless steel tubes.and the surface quality and dimensional precision is substantially improved.Based on the conditions of tension tube reducing machines(rolling force,speed ,tube diameter)what is recommended is the use of either integrated roll rings or composite roll rings ,achieving a good performance-price ratio. ˇˇˇˇOptional cemented carbide grades:YGR55 YGR60 For properties see the Table above.
